An alkyne has seventy-five carbon atoms in its molecule. The number of the hydrogen atoms in its molecule will be :

(a) 150

(b) 148

(c) 152

(d) 146

Solution:

Option (b) is the answer.

The number of hydrogen atoms in an alkyne molecule with 75 carbon atoms is 148. Alkynes have the generic formula CnH2n-2, where n is the number of carbon atoms in each molecule. The number of hydrogen atoms in alkynes is 148 when n = 75 is substituted in the formula.
